The resource description framework (RDF) is a specification that applies conceptual modeling techniques to provide a structure for data in which its elements may be linked with one another according to their relationship. Such data structures may provide enhanced utility by improving search capabilities and/or developing a context from which to infer other aspects of information that may not be included in the data while in its raw form. RDF databases have been developed that store data according to the RDF specification. Access to data from these databases is provided by a RDF query language commonly referred to as the SPARQL Protocol and RDF Query Language (SPARQL) query language.
